What creature does the Eurasian Wryneck deliberately mimic during its defensive display?
Answer
A snake.
The Eurasian Wryneck employs a highly specialized and memorable defensive strategy when it feels threatened, serving as a potent second line of defense after its initial camouflage fails. This display involves dramatic physical actions: the bird fans out its wings and tail, emits a loud hiss, and begins to jerk its head spasmodically from side to side. The combined effect of the hissing and erratic, jerky head motion is intentionally orchestrated to create a startling illusion that the bird resembles a snake. This snake-like mimicry is designed to deter predators by suggesting danger or toxicity where none exists.
